Application July 3, 1939, Serial No. 282,699

Claims.

My invention relates to fountain brushes and' collapsible tube holders of the character embodied in my co-pending application, Ser. No. 252,807, filed January 25, 1939, which are more particularly adapted for dispensing and applying polishing paste to shoes.

It is the purpose of my invention to provide a combined fountain brush and tube holder which is characterized by its structural simplicity, low cost of manufacture and easy mode of assembly and disassembly of its parts to permit the removal of an empty tube and the insertion of a filled tube.

It is also a purpose of my invention to provide a device of the above described character wherein the nozzle of a paste tube is employed to secure a tube holding frame in axial alinement on the brush so that the tube in turn is held in axial alinement with the brush by the frame.

A further purpose of my invention is the provision of a tube holding frame which may be stamped from a single piece of metal to form a pair of companion frame parts integral one with the other, thereby eliminating separately formed frame parts hingedly associated one with the other and the attendant increased cost of manufacture.

Another purpose of my invention is the provision of a tube holding frame which has a pair of arms connected at one of their ends by a spring means which allows contraction of the arms for coupling to the brush head, but automatically expands the arms when uncoupled from the brush head to release the collapsed paste tube and thus facilitate its removal.

I will describe only one form of fountain brush, collapsible tube, and tube holding frame, individually and collectively embodying my invention, and will then point out the novel features thereof in claims.

In the accompanying drawing:

Fig. 1 is a view showing in side elevation one form of combined fountain brush and tube holder embodying my invention, with one form of tube in place within the brush and holder.

Fig. 2 is a view partly in section and partly in elevation and taken on the line 2-2 of Fig. 1.

Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a fragmentary view partly in section showing the tube embodied in my invention.

Referring specifically to the drawing, my invention in its present embodiment comprises a fountain brush including a head l5 formed of hard rubber or similar material, and provided with an annular groove [6 in which bristles H are permanently secured in a suitable manner to form a brush. The head I5 is formed with a bore which extends completely therethrough to afiord communication between one end of the head and the bristles. This bore has a portion I8, at the upper or inner end of which is a counter-bored portion l9 to provide at the junction of the two an annular shoulder 20. A feed tube 2| is received in the bore [8, and a flange 22 on the upper end thereof seats on the shoulder 20. The lower end of the tube is slit as at 23 to provide an outlet through which paste is adapted to be discharged between the bristles ll.

The counter-bore I9 is screw-threaded for the reception of the nozzle of a tube, as will be described hereinafter. Above the counter-bore 19 the brush head is formed with a second counterbore 23 to provide an intervening shoulder 24 of annular form.

My invention also includes a holding frame for a collapsible tube, and this frame is structurally characterized by one piece of metal or other suitable material shaped and bent to provide a pair of companion arms 25 connected at one end by a bight 26 which is resilient in order that it may function as a spring to urge the arms 25 to the expanded position shown in dash lines in Fig. 2. The other end of each arm is constructed to provide a laterally extending enlargement 21 on the edge of which is formed a collar 28. The two collars are of arcuate form and each provided with an angular lip 29, the function of which will be described hereinafter.

My invention also includes a collapsible paste tube 30 provided with a screw-threaded nozzle 3| at the base of which is formed an annular shoulder 32. It will be noted that the nozzle 3| is relatively large in diameter as compared to the nozzle for the conventional collapsible tube. This is for the purpose of precluding the association of the conventional tube with the brush of my invention or with the tube holding frame.

To assemble the brush, frame and tube so that they occupy the respective positions shown in Figs. 1 and 2, the tube 30 is placed between the arms 25 of the frame so that the nozzle 3| extends between the collars 28. Now by contracting the arms 25 to the solid line position shown in Fig. 2, the collars 28 are brought into engagement with the nozzle in such a manner that the lips 29 abut the shoulder 32. With the tube and frame so related, the tube nozzle 3| can now be screwed into the counter-bore [9 until it abuts the flange 22 of the feed tube 2|. In this position of the nozzle the shoulders 24 and 32 are in opposed relation, and with the lips 29 interposed between such shoulders, they are firmly clamped between the tube and brush head. As so connected, the frame is secured against withdrawal from the brush head and in holding relation to the tube 30, whereby both the tube and frame are secured in axial alinement with the brush head. The side wall of the counter-bore 23 serves to prevent any outward movement of the collars 28 so that the arms 25 are held in contracted position to hold the tube on the .brush head so that such tube can not be moved laterally in any direction.

With the parts of the device assembled as described, collapsing of the tube 30 through operation of a conventional key 33, the paste con-' tained within the tube can be expressed there-. from through the nozzle 3| into the feed tube 2| and'through the outlet 23 between the bristles of the brush.

To disassemble the parts of the device incident to replacing an empty tube with a filled tube, the nozzle 3! is unscrewed from the brush head to detach one from the other. As soon as the nozzle has been unscrewed to a point where the collars 28 have been withdrawn from the brush head, the spring bight 26 functions to expand the arms 25 to the dash line position in Fig. 2, thereby releasing the tube 30 and permitting its ready removal from the frame.

Although I have herein shown only'one form of fountain brush, tube holder, and tube, em-

bodying my invention, it isto be understood that various changes may be made herein without departing from the spirit of my invention and V the spirit and scope of the appended claims.

I claim:

1'. In combination; a fountain brush having a within the bore and engaged by the nozzle for securing the frame in the socket and against longitudinal and transverse movements relative to the brush.

2. In combination; a fountain brush having a bore; a tube having a nozzle threaded in the bore; opposed shoulders in the bore and on the nozzle; and a holding frame for the tube having arms, collars on the .arms disposed between the opposed shoulders for securing the frame to the brush, and spring means tending to expand the arms and collars so that when the collars are free of the bore the arms and collars will spread to facilitate removal of the tube from the frame.

3. In combination; ,a fountain brush having a bore provided with an annular shoulder at its entrance end; a tube having a nozzle threaded in the bore and having an annular shoulder at thebase thereof so as to be disposed in opposed relation to the first mentioned shoulder; and tube holding arms having elements thereon disposed between said shoulders so as toibe gripped by the latter for securing the arms in tube holding position on the brush.

4. In combination; a brush having a head provided with a bore therethrough a part of which is screw-threaded and another part counterbored, tube holding arms adapted to engage a collapsible tube having a threaded discharge nozzle adapted for engaging the threaded part of said bore, while terminals'of said arms extend into and engage said head and tubeand said counterbore to retain the arms in tube holding position.

5. In combination; a brush having a head formed with a bore therethrough a portion of which is screw-threaded to receive the threaded nozzle of a collapsible tube; and tube holding arms having one of their ends extended into the bore between opposed portions of the tube and bore; and means connecting the other ends of said arms operating to spread the arms upon detachment thereof'from the head.
